If given a set, it awaits an attribute <literal>type</literal> which can be either <literal>normal</literal>

|

For <literal>normal</literal> mode you can specify <literal>python2Packages</literal> and

<literal>python3Packages</literal> as functions from libraries set into lists of libraries.

For <literal>emperor</literal> mode, you should use <literal>vassals</literal> attribute

which should be either a set of names and configurations or a path to a directory.
